If we except the last section, the species of this genus are readily known by their
elongated fruit, separated by constrictions into one-seeded joints. This structure
occurs in no other genus of the Order. We "have, however, abstained from, intro-
ducing it into the generic character, because we are unwilling for the present to
separate from the genus several species in which the fruit is unknown, and one at
least in which it is not jointed. All these species agree with the more typical Unona,
in the thin, more or less elongated petals, in the shape of the ovary and style, and in
the ovules being definite in number, and inserted into the ventral suture in a single
row. These characters appear to us constant, and they are, we believe^ sufficient to
characterize the genus, without its being necessary to have the fruit. One
or two species are scandent, while the majority arc erect j but there js a great simi-
larity in general aspect in all. The young leaves and petals are always pellucid-
dotted. When the ovules are reduced to two, the genus approaches very close to
Pofyalt/iia, but is readily distinguished by the position of the ovules. That genus is
also well marked by the nervation of the leaves, which is peculiar, and very diiferent
from that found in Unona. The section Dasymaschalon is remarkable for'the entire
suppression of the inner petals, but its habit is quite that of the typical Unoua; and
the other characters (especially the fruit) are so identical, that if does rot appear to
us advisable to separate it. TJnotia is entirely an Asiatic peuus, nor do we know
any species in addition to those described below, except U, virgata, Blume, which
appears to be referable to our section Pseudo-Unona.

The fruit is only kuowu from Roxburgh's description, unless Umria faterocarpa,
Bl. FL Jav. Anon, 41.1.17. belongs to this species, which, from the general resem-
blance, is probably the case. I hesitate, however, to quote that specie^ because it has
stellate hairs, which 1 have not found iu the plant now described; they are, however,
very densely compacted, and may occasionally be stellated. Blume's ^laut h from
Java, but of doubtful locality. The carpels are pubescent, and have from one to two
joints, of tlie size of a pea, the terminal one mucronate.
